Chapter 3. Operation

IARP (Inverse ARP)

Write Security: 3; Read Security: 5

The Inverse ARP (IARP) field is only present when this is a frame-relay network interface. ATLAS always responds to Inverse ARP requests with its IP address for the requested DLCI.

Enable Atlas sends Inverse ARP packets in order to determine the IP address on the other end of the virtual circuit. If the Inverse ARP packet is responded to, a route is placed in the IP route table.When this field is set to ENABLE, ATLAS dynamically sends Inverse ARP packets to deter- mine the IP address on the other end of the virtual circuit. When an Inverse ARP packet is not responded to, a route is placed in the IP route table.

Disable ATLAS responds to Inverse ARP requests with its IP address for the requested DLCI. If set to DISABLE, ATLAS does not generate Inverse ARP request packets. In this case, the Far-End Address parameter may be used to statically assign a route address (see Far-End Address on page 3-8).

Far-End Address

Read Security: 3; Write Security: 5

The Far-End IP Address field is only present for frame-relay network interfaces, and it is only selectable when Inverse ARP is disabled. The IP address of the device on the other end of the virtual circuit may be specified. A static route to the far-end network will be added using the interface Subnet-Maskif nonzero. If

0.0.0.0has been specified for the Subnet-Mask, a default subnet mask is used based on the class of the Far-End Address. (See also Subnet Mask on page 3-7.)

MTU (Maximum Transmit Unit)

Read Security: 5

Defines maximum number of bytes in a datagram transmitted over this interface.

RIP (Routing Information Protocol)

Configures RIP on this interface.

Mode

Write Security: 3; Read Security: 5

Allows RIP to be enabled or disabled on a per-interface basis.

Tx Only RIP advertisements are periodically transmitted, but are not lis- tened to on this virtual circuit.

Rx Only RIP advertisements are not transmitted on this virtual circuit, but they are listened to.

Tx and Rx RIP advertisements are periodically transmitted and are lis- tened to on this virtual circuit.

If mode is Off, the following menus will not be visible.

Protocol

Write Security: 3; Read Security: 5

Sets the version of RIP being used on this interface. The options are RIP V1 and RIP V2.
